Imagine stumbling on a 6,000-year-old conch shell, blowing into it, and getting a blast as loud as a chainsaw! Archaeologists in Spain did just that and discovered these shells were likely used as prehistoric megaphones for long-distance communication. Some could even play a few notes, but the main takeaway? Our ancestors knew how to make some serious noise way before the vuvuzela. Who knew ancient tech could be this loud? #Science #archaeology #ancienttech
